AB Cylindrical lenses are promising devices for a wide range of applications [1-3]. This kindof lenses can be used in some novel applications such as light-sheet microscopy, lineillumination microscopy or autostereoscopic devices. However, as any kind of lens, the maindrawback is the generation of optical aberrations. These aberrations determine the imagequality of an optical system. Interferometrists often like to represent wavefronts as Zernikepolynomials. Zernike polynomials have been widely used because, unlike other polynomialset, they are orthogonal over a unit circle and represent balanced classical optical aberrations,yielding minimum variance over a circular pupil [4]. These characteristics are lost when noncircular pupils are employed. Some research works have developed new coefficients fordifferent pupils [5]. Notwithstanding that, they were targeted for rotational symmetric optics[6]. In the referred paper, 2D Chebyshev polynomials related to some Seidel aberrations aredescribed. These ones form a useful orthogonal basis for optics of rectangular apertures,making them an attractive option for cylindrical lenses.In this work, optical aberrations in a liquid crystal (LC) cylindrical lens have been modeledand measured, for the first time. We have developed our own application specifically toextract the 3D wavefront from an interference pattern. This software tool also allows us toobtain the optical aberrations based on Chebyshev polynomials. A tunable LC cylindrical lenshas been designed and manufactured. Optical aberrations have been assessed by adjusting thecontrol voltage applied to the device.
